They stick up about an inch or so in the tank. Would take a lot of junk in the tank to block this filter.

Tom, please tell this guy that does not know much about this subject, what you mean by "lapping". Sorry, I think you may have done this before but the old mind forgot.

Re: Model A Zenith Carburetor
I don't remember if I spun it some in my lathe and used a little crocus cloth to help polish it, but I do remember using toothpaste and turning it by hand. I think I may have used fine valve grinding compound, then toothpaste. I then gave it a thin coat of grease and installed a new shaft seal kit from one of the parts houses, Bert's, Bratton's, and Snyder's.
Before doing this the handle was hard to turn, and ever since the lapping and greasing, it is very easy to turn. |

Re: Model A Zenith Carburetor
Here is a quick fix for a leaky gas shut off value. I put one of these things on my huckster years ago. The short term advantage is that you do not have to drain your gas tank. But the long term disadvantage is that you have to turn on two dxx values every time you start your rig. Most vendors carry these things if you are interested. This is on my 29. Don't know if these work on 30/31's.

Re: Model A Zenith Carburetor
I use mineral spirits when bench checking float levels and float valves. Works well and I think safer than gasoline albeit still flammable. It has always worked well for me.

Re: Model A Zenith Carburetor
I have the shut off valve that is shown in post 27 and since I installed it, I have not moved the original shut off valve at all. I just leave it open and use the new one which is a 1/4 turn ball valve and much better than the original. It will not leak and so when I park our A at night, in the garage, I shut off the gas and let the engine run for a couple of minutes and then shut it off and have no gas smell or leak at all. If you happen to have a carburetor that leaks through the casting and you don't want to purchase another one right now, then when you turn off the gas with the new valve, just run the engine until it empties the carburetor completely and stops running. When you next drive your A, turn on the new gas valve and let gas run down into the carburetor before you crank it over. Ernie

Re: Model A Zenith Carburetor
So far only one person has posted a link that talks about float level. If the float level is correct and the float valve at the carb is working it will or should not matter if the shut off valve is left open or closed. Unless the float valve is not sealing to the upper casting or there is a crack or porous casting. No word from original poster.
Lots of good information given here, but it has been 6 day and not a word from the original poster. I for one am wondering if the question is for real. I see a number of postings in the "Questions and Suggestions" section by one time posters that A; on the surface look real but generally are just a little off and B; when told to ask in the correct forum never do. I hope this is not the case and any and all information that has been give help him or others.

Re: Model A Zenith Carburetor
I have read all the posts and as a result I went back to check the manual shutoff valve. I removed the gas line between the settling bowl and carburetor and hung a can to catch any leaks. The first overnight I had about a tablespoon of gas in the can and the second night I had about 3/4 of a teaspoon in the can. I decided to order an electric shut off valve from Snyders to try this. I will install it when I receive it let you know. The present manual shutoff valve is less that 1 year old.

Re: Model A Zenith Carburetor
Are you using the screen in the tank valve?
I consider it a "must have". |

Re: Model A Zenith Carburetor
Yes, I have the screen in the tank valve, the screen in the carburetor and a cartridge filter in the line after the settling bowl. I want to thank everyone for their input on this problem and I have learned a few new things to check from your input.

Re: Model A Zenith Carburetor
I am new to this forum so I am sorry that I did not reply sooner. I guess it did not occur to me to reply sooner and I will try to respond sooner in the future.
